我做了一个简单的开关盒(以前没用过...所以请耐心等待)。
select_diff.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
@Override
public void onRatingChanged(RatingBar ratingBar, float v, boolean b) {
rating = (int)(select_diff.getRating() * 10);
Toast.makeText(timestables.this, Integer.toString(rating) , Toast.LENGTH_SHORT).show();
switch (rating) {
case 10:
questions.setText("10 Questions.");
time.setText("10 Seconds For Each Question.");
timestables.setText("2 to 5 Times Tables");
case 15:
questions.setText("13 Questions.");
time.setText("8 Seconds For Each Question.");
timestables.setText("2 to 6 Times Tables");
case 20:
questions.setText("15 Questions.");
time.setText("7 Seconds For Each Question.");
timestables.setText("2 to 7 Times Tables");
case 25:
questions.setText("20 Questions.");
time.setText("6 Seconds For Each Question.");
timestables.setText("2 to 8 Times Tables");
case 30:
questions.setText("25 Questions.");
time.setText("5 Seconds For Each Question.");
timestables.setText("2 to 9 Times Tables");
case 35:
questions.setText("30 Questions.");
time.setText("4 Seconds For Each Question.");
timestables.setText("2 to 10 Times Tables");
case 40:
questions.setText("35 Questions.");
time.setText("3 Seconds For Each Question.");
timestables.setText("2 to 11 Times Tables");
case 45:
questions.setText("40 Questions.");
time.setText("2.5 Seconds For Each Question.");
timestables.setText("2 to 12 Times Tables");
case 50:
questions.setText("40 Questions.");
time.setText("2 Seconds For Each Question.");
timestables.setText("2 to 12 Times Tables");
}
}
});
变量“ rating”的类型为INT。来自Android的Toast始终显示正确的大小写值(即,当我选择2星时,它敬酒“ 20”),但未设置文本框...仅出现大小写45(出于某种原因:S?)无论您选择哪种评级,都可以使用。
您需要在每个案例的末尾添加break语句,以避免在遇到第一个案例后再进入每个案例。
看到这个。
